What is ISO 4210-10 about?
ISO 4210 is a series of international standards on electrically power-assisted cycles that discusses the safety requirements of bicycles. ISO 4210-10 is the 10th part of a series of documents on EPAC. ISO 4210-10 specifies safety and performance requirements for the design, marking, assembly, and testing of two-wheeled electrical power-assisted cycles (hereafter EPACs), fully-assembled EPACs and subassemblies, and provides guidelines for information supplied by the manufacturers (i.e. instructions on the use and care of such EPACs).
ISO 4210-10 applies to two-wheeled EPACs that have a maximum saddle height of 635 mm or more and are intended for private and commercial use with exception of EPACs intended for hire from unattended stations.
